With Shopify you don't pay ~20% sales commission to Amazon per se, but you sure as heck will end up paying for that if not more to Facebook.
Where by FB has no direct incentive, yet. It could be a FB Marketplace PM team someone has already copied Shopify outright and is just waiting for the right time to roll that out to all FB user worldwide.
With Amazon Marketplace the strategy has always been to convert customers off that platform into your own.
Most top listings in most niches/categories are priced for break even inclusive of the multitudes of keyword PPC campaigns they're running with the hope that you leave a review and that you actually pay attention to the little postcard that comes inside the package asking you to register your email address.
